Specification forming part of Letters Patent No. 79,868, dated July 14, 1868.

To all whom it may concern:

Be it known that we, 0. L. SHOLES, (313-.

I Los GLrnnEN, and S. W. Sonmt, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented-certain new and A useful Improvements in Machines for Writing or Printing Correspondence; and we do hereby declare thatthe following is a full, clear,

and exact description thereof, reference beinghad to theaccompanying drawings, making part of this specification and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

"of our improvementsconsist of a circularannular disk, provided with slots-andgro yes to hold and guide the type-bars; a conce tric groove around the periphery of the dis to hold, support, and guide the pivots o :the type-bars; the combinationof a slotted 0 rolllar disk with type-bars fitted and piv' ted-l thereto; the combination of rods, levers .=and keys for working the type-bars; a carriage combined and provided with a pivoted pawl, arm, and pins, and attachments to mov the paper vertically and laterally, and the c nbiination of a rod and clamps tahold-the paper fast tothe carriage. I

.In the drawings, Figure 1 represents a top view of our machine; Fig, 2, a transverse vertical view of a section thereof, taken through the middle on the line as aof Fig. 1; and, Figs. 3 and4, a view of detached parts thereof.

Of any hard, tough material (we prefer and use brass) make and turn a disk, 0, four to five inches in diameter, more or less, accord ing to the length and number of the type-bars to be used, and one-half to three-fourths ofan inch thick, or more, at the periphery or outer edge, according to the width of the type-bars. Through the center of the disk bore a'hole one to one and a half inch in diameter, as de-. sired, to let the top or raisedsidesof the inner ends of the type-bars strike through against the paper and platen when in use,

Plane the top side of the disk smooth and level, and bevelthe bo'ttom side from the periphery t0 the circumference of the hole in the middle, or from the outer to the inner edge, to a thickness of two-eighths to three-eighths of an inch, as preferred. Through the outer edge of the disk, from side to side, and one-half t0 three-fourths of an inch deep, or in toward the center, cut a series of slots, S, as many as the letters or characters to be used in writ-in g. In the bottom .side of the disk out a series of ra dial slots or grooves, S, in aline directly from the central point exactly to meet and fit in with the slots in the edge, as manyradial grooves as characters to be used ingwritlng,

or as slots in the edge. In and around the outer edge or periphery cut or turn a, groomer or slot, to receive [and hold the pivot-wire on which .to pivot'and suspend the type-bars.

- Make as many type-bars or hammers D as '1 radial grooves in the disk, or characters to he used in writing, of any suitable substance, (we

prefer and use steel,) exactly to fit and work readily and smoothly in the radial grooves and slots, and pivot the outer ends into the slots bya wire, 0, running around in the groove or slot circuinscribin g the periphery, and through pivot-holes bored in-the ends thereof, one wire 1 serving to pivot all the type-bars, so that when not striking they will hang down. On the top sides of the inner ends of the type-liars cut or stamp raised types i, the types to he at such angles tothc type-bars thatithe perpendicular lines of the letters made by the types will be parallel, and thelbottom horizontal lines of all the letters will be on one and the same line, and so of the top horizontal lines.

The edge slots inthe periphery of the disk are not vitally essential to its yalue, though preferable and adding to it.

In the middle, or as nearly as desired, of

any table, A, of suitable size and material, mounted on any practicable and convenient frame or stand, B, cut out a circle large enough to receive the disk. Fasten the disk in the circle by any convenient way soas not to interfere with the free working of the type-bars and rods and levers. Over the central point,

in the circle of thedisk, hang a platen or block, E, by any practicable means which will old I tdthe'fsidebf'thetable; Hang. the platen as {near rhe ra'emv the'disk as will" just 'adi'nit' the free s'lidingof the. paper. to be written on be- 'tween it andjthef-dislt; 1 In; the l'ower part of. ihthefram'e Bi'placofa seifies of levers, K,, one' t mbre ;than .as many as. there are type-bars;

other end of each of the levers .toeach of the type-bars by a wire or rod, I. So arrange the keys andzleversand rods, andfonnect them with the typevbars in the peculiar manne'r'represented ,inthe drawings in Figs. 1' andZ that' when a key'. is struck it will throw the',,eorre spending typeup against the platen, the type bar instantly falling 'back to its suspended po i sition, till the key is struck or pressed again.

, By placing white paper over. the disk and under the platen, and an inked.ribbon oican' 'boniz'ed or manifold paper between the'white paper .and the platen, and striking the type up against the paper and platen, the letter will be printed on the top side of the white paper.

On the top, of the table put a carriage of two parts, P and P.- To-P attachan arm, y, to project baek and fit in agroove in the rear part of the arm F, and then flxa springer, to" press against it, 'to'keep-it from moving ac-w cidentally. Ing'the under surface of the front.

edgeof the plate 1 cut ,a,groove,'and into which loosely fit the turned up edge of the.

plate If, as shown in Figs. 1 and 2, to form a guide to cause the platePto move in a straight line, and always keep it connected withthe plate P so that when the latter is moved to or-from thefront of the table, the :latter'will be moved with it. Attach to the arm F one end of a rod, V,-and attach the other end to the table A. -On 'thisrod mount a sliding guide, 1). Connect this latter to the part P *by a tube, p, fitting on the rod U, and fasten the latter to P.

Under the rod V place a pulley, t, and underthe table fasten the drum W arodfid which to wind a cord passing over th pulley, and. operate" the drum by a weight, L, as shown in Fig. 2. On the same shaft with the drum mount an escape-wheel, h, with a ratchetwheel, 0, attached, and connected by a pawl,

0. To an arm, Y, piv'ot an escape-lever, H,

' having two pawls, G, arranged to engage with the escapement-wheel W, to regulate the movement of the drum when operated by the weight L, and thereby the movement of the'paper-carriage P. Slot the rear end of the detent-H, and en gage it with a rod or bar, 1', resting on the inner ends of the keys J, one end extending to the front of the table,.along side of the keys, and terminating in a handle or key, I, as shown in Figs. 1 and-2. As this --2. v apses rod rests over andon, all the keys, as shown by the dotted line in Fig; '1, whenever a key th-zWlieel-h, with the drum W, will be allowed to-niove the extent of one tooth, and

will movethe paper-carriage the width of one letter.. The handle or key I, beingthe extra }key, or key without the. corresponding type,

striki'ng it, will nove the'pja-per the width of a .letter without striking 'a type, and give the proper spacebetween words. ';A ttach a cord the weight R, at ione end,* to the'guide pyas shown in. i thence along thesarm F, and down over another pulley; a, to'prevent the paper-carriage from moving accidentally ortoo far. On the un} der'side of: the armi F, at'e'q ual and uniform p'distancewehdistanceor space the desired widthfromdine to'line in writing-arrange a series of pins, jc, as. shown in Fig. 2 ()n the carriage P pivotthe pawl e, as shown in Fig. 1, .with the front. end curved, and attach a topress the back end against a pin I Aftertheean'iagehash'eenmovedforw ard,in

'writin'ga line'foif-otherwise, in being moved, back tothe place of beginning the convex side oftho-curved end of the pawl es'trikes the backside of one of the pins 0,.and thereby'moves the carriage P,.withthe-part 1?,to-

ward. the back side of the table, or at aright an gleto the line of writing, the distance from pin to pin, or the width of a line, the spring n permitting the pawl e to 'yieldas it hits- ;ag'ain'st the succeeding pina, as the carriage is moved forward again, and the arm 3 of the plate P. working in a groove or otherwise, to guide. the plate P and the wholebarriag'e. Attach to the carriage P the clamp u, large enough to go round the margin of the paper to be used to write on,- as shown in Fig. 1. Fasten one end or side of the clamp to the car riage with hingesh, and the other end with catches or buttons m to slip over. I v

To work the machine, in the process of writing', first lay down on the carriage the paper to be written on. Over this lay a sheet of carbonized paper or inked'rib'bon or cloth, and bring down the clamp u to hold them securely to the carriage. Then strike the keys in the order of the letters tospell the words to be written, using the handle or key I to separate the words by proper spaces. Whatever key is struck, the corresponding letter or character will be printed on the upper side of the paper, and as each letter is printed, the I paper is moved forward by theaction described, ready for the next-letter or proper space.

Thus made, the type-writing machine is sim -ple,fc0,mpact, and reliable, and entirely feasible; and practicably adapted to the purpose intended, which is writing ordinary communications with printing-types instead of a pen; and f f What we claim as new and useful in our'invention isas follows;
